v To all whom t may concern:

Be it known that I, DEE DEMPSEY, a citizen of the United `States, residing at Mace,

in the county of Shoshone and VState ot' idaho, haveinvented certain new and useful y Improvementsin Dumping-Cars, of which y the following is a specification.

rlhe presentinvention relates toimprove-` ments 1n dumping cars for use on railways, and is designed particularly for use 1n connection with flat cars, gondolas, etc.

The invention contemplates the construction and operation of the movable carjloor so that fthe material may be dumped.. either between the `rails o the track upon which thecaris standing, or at the outer sides of the rails of the track, as desired.`

l'llhe cars and their operating parts vare so constructed that a train olsuch cars may rst be uncoupled one car from another, and

- then by utilizing the locomotive to draw upon certain elements of the operating de-` vices, themovable portions of the car l-loors are tilted, either inwardly or outwardly, as the case may be, to dump the material, after which the locomotive is backed up to `restore the l,movable floor to closed `or normal position. After the cars have been dumped, the cars are coupled together in the usual way t0 Vvcompletethe train, and the train of empties is then hauledaway for another load.,` To this end, the cars are first uncoupled in usual manner, land then a special coupling, forming part of the invention, is made between the separated cars, and a'l'ter the material is dumped, and as the cars are coupled in usual way, the special couplings Inayreniain closed, or opened as desired.

ln f the accompanying drawings one complete example of the physical embodiment of the inventionis illustrated,.constructed and operated according to the best mode so far devised forthe practical application of theprinciples of ,the invention. l l

`In the accompanying drawingsa standard type of railway fiat car is depicted having the usual wheels 1, the truck T of the four wheel type,` and the usual automatic end couplers 2 by which the cars are coupled when the trainis moving, but which cou-` plings are opened, as in Fig. 2 when the train of cars is to be dumped. n l

The sides 3 of the car are shown as of metal, as are also the ends 4, and the fixed portion 5 oi` the car floor is also of metal in the preferred ornrof the invention.

Extending longitudinally of the car, and at the sides of the center beam 6, are rectangular openings 7, 7, that are normally closed by the floor sections or tilting panels 8', and it should be understood that these panelsomay be tilted either with their cenf` ters toward the center of the car, or with their centers toward the longitudinal outer edges of the car. These tiltable floor sec tions 8 are also of metal, and each section has a cylindrical head or bar as 9 and 10 extending along its inner and outer edges respectively and adapted to engage, in normal position, in the rounded recess or groove 11 Iextending the length of the respective floor sections along the longitudinal edges of theopenings 7l at 'the sides ofthe center of` the car floor. rlhese bars and grooves form the pivot or tilting centers of the floor sections when the material is being dumped.

The `floor sections or car bottoms areJ dumped, either towardthe center of the car joining cars at each end by means of cou' side beams 6 from which they are supported, pivotally, through the instrumentality of the rock bars 16 and 17 and 18 and 19 at the center and sides of the carsfrespectively, see Figs. 1 and 4. The center and side beams are slotted to accommodate these oscillatable suspending blocks, and the blocks are recessed or grooved at 11 to receive the heads or bars 9 and 10 of the sections and hold them up in the slots 11 in the iiXed portion of the car floor. The sections are, opened and the material dumped through the medium of three draw bars 20, 21 and 22, the bars'20 and 22 being located at the sides of the car and the bar 21 at the center of the car, and supported in bearing blocks 23 so that these bars may be pulled 0r drawn longitudinally of the car, so that when drawn theload is dumped, andwhen pushed, the car sections will be closed. These bars are coupled together with the adpling sleeves 24, links 25, coupling pins 26 and sockets 27. The sockets are attached at one end of va car, and the sleeves are attachedv at the other end of the car to their draw bars, the link having a head 28 movable within the sleeve so that there is a lost motion between adjoining cars in the motions of pushing and pulling.

The ycenter bar 21 is adapted to operate the floor sections to dump the material between the rails of the tracks, and the side bars 2O 22 are designed to drop the floor sections to dump the material outside of the rails of the track, and Figs. 1 and 4 show the parts dumping between'the rails of the track,y and the coupling made at the center of the ears.

The floor sections drop when they are released, and they are released by the oscillation or rocking of the shafts 16 and 17 to dump the material as indicated in Figs. 1 and 4 and in detail in Fig. 5, the suspending blocks 12 and 14 having been turned by their rock shafts to permit the floor sections'to swing downwardly and outwardly.

heads, as the case may be.

These shafts are normallyh'eld with their blocks in supporting position, by means of the coiled springs 29 that are attached at one end to a shaft and at the other end to the end of the car,'but of course the weight o-f the load overcomes the springs when the section is released and the section dumps its material.

The floor sections are supported, each by a crank shaft or bail as 30, 31,. suspended longitudinally from the under side of the floor of the car' and adapted to swing laterally of the car to lift the iioor sections and swing them on either of their pivot bars or Each bail is provided with a pair of rack; pinions 32, 38,

located between the transverse beams 34 of' the car frame, and each pinion of course has a pair of rack bars, as 85 and 36 which are held to their pinions by the rollers 37 on shafts 38 journaled in the transverse beams 34. It will be noted in Fig. 4 that the rack bars 36 are pivotally connected by links 39 to the center draw bar 21, and the two lower rack bars 35 are similarly connected by links 40 to the two outer draw bars 20 and 22. Thus the center draw bar operates the iloor sections to dump the material between the rails of the track upon which the car is standing, and the two side draw bars operate the floor sections to dump the material outside the rails of the track upon which the car stands, the pinions having pawl and ratchets 41 and42 (see Fig. 6) so that they willl operate through the rack bars in one direction only.

In Fig. 5 it will be observed that the suspending block 14 has been turned, by the swinging actionV of the iioor section, to open position, and it is held in that position while the floor continues its swinging movement, by the latch 43 engaging the notch 44 in the block, and an operating lever 45 of this latch will be actuated by a spring pressed vactuating lever or arm 46 as the floor section swings up again, freeing the block and rock bar so that spring 29 may rock the shaft 16 so that the block will fol low the section 8 and close up against the underside of the head or bar 9. There are four sets of these latching devices, a set at each side of each floor section, and they are designed to hold the suspending blocks 12, 13, 14, 15 in position, While the floor section is open, to be returned to operative position after the section has been closed.

The floor sections are prevented from falling or being displaced by the pivoted links 47 connected at the corners of the sections andA pivotally connected to the car frame, the links being of suficient length to permit free movement of the sections in dumping or being returned to closed `posi tion.

To prevent accidental actuation of the dumping devices, locking levers 48, 49, 50, notched at 51 and pivoted at 52 at the end of the car, are provided to engage the three 115 draw bars 20, 21 and 22 and hold them against longitudinal movement.

In operation the cars are equally adapted for use in hauling and dumping coal, sand, or gravel, and the cars are specially adapt- 120 ed for hauling ores from the mines to the smelter. The cars' are loaded andhauled to their dumping place, and then the couplings 2 are opened and the brakes on the cars are set, and the engine started ahead, 125 it being understood, of course that the center draw bars 21 of the cars are coupled tothe adjoiningr cars, as indicated in Fig. 4,. when it is desired that the cars shall dumpy between the rails of the track. Wheny the ma- 130 terial is to be dumped outside the rails of the track, the center bar will not be used, but the two outer bars 20 and 22 are connected with the adjoining car. When the engine draws the train, as in Fig. 4:, to the left, the links 39 pull the rack bars 36 36 toward the center of the car and the pinions 32 are revolved causing the crank shafts or bails 30 31 to swing downward to permit the ioor sections to swing open by the weight of the load thereon, and the sustaining or suspending blocks are carried with the Hoor section until they are caught by the latch 43 and held. After dumping the engine is backed up to couple the cars together and this action also returns the bails to position, opens the latch and permits the springs to swing the sections to locked position where they are held by the sustaining 0r suspending blocks.

What is claimed herein is:

l. The combination of a railway dumping car having freely pivoted floor sections and supporting means therefor, draft means on the car adapted for actuation by a locomotive, and connections between said draft means and supporting means whereby the latter means is withdrawn to permit dumping of a load.

2. The combination in a train of dumping cars each having dumping floor-sections, of'

means for coupling'l the cars together, and connections from these coupling means whereby the dumping floors are released to dump a load.

3. The combination in a train of railway cars each having a reversible, dumping floor section at the sides of its longitudinal center, a plurality of coupling devices carried by each car and adapted to couple with an adjoining car, and connections between said devices and sections, whereby the loaded sections may be selectively dumped..

l. lhe combination with a car Hoor, of a pivotal iioor section, a resiliently supported rock shaft and suspending blocks thereon for the section, a supporting member for the section when loaded and draft means on the car for releasing the supporting member.

5. rlhe combination lwith a car floor, of a pivotal iioor section, a resiliently supported rock shaft and suspending blocks thereon for the section, a supporting member for the section when loaded and means on the car for releasing the supporting member.

6. rlhe combination with a car floor, of a pivotal floor section, a resiliently supported rock shaft and suspending blocks thereon for the section, a supporting member for the section when loaded and a draw bar and connections between said bar and the supporting member for releasing the supporting member.

7. rlhe combination with a car floor of a reversible, pivotal floor section, a pair of resiliently supported rock shafts and suspending blocks thereon, a supporting member for the section, and selective draft means connected with said supporting member for releasing the loaded section.

8. The combination with a pivotal floor section and a rotary supporting bail, a pinion on the bail, and a rack bar engaging the pinion, of a draw bar and connections between said draw bar and rack bar, and means for actuating the draw bar.

In testimony whereof I affix my signature.
